The LG-UHT plate UHT sterilizer treats liquid dairy, tea and juice at 137℃ with a 3–5 second hold, matched to aseptic filling. Available from 1000 to 5000 L/H with PLC touch-screen control and high heat recovery, it is a proven sterilization core for export beverage and dairy production lines.
Dairy and beverage producers targeting long shelf life without losing fresh taste face one core question: which sterilizer pairs cleanly with aseptic filling? The LG-UHT plate UHT system is built for exactly that role, serving plants across Central Asia, Africa, Southeast Asia and South America as the heat-treatment heart of a turnkey drinks or dairy line.
It drives product to 137℃ and holds it for only 3–5 seconds – long enough to wipe out harmful microbes, short enough to protect nutrition, colour and flavour. Hot-fill with automatic discharge-temperature control and cold-fill routes are both supported, so the unit adapts to whatever filler follows it.
Overview
Plate-stack heat exchange gives the LG-UHT a high heat-recovery rate inside a compact, tidy footprint with steady temperature control. A PLC and touch-screen HMI run the whole cycle automatically, delivering reliable unattended operation across the 1000–5000 L/H range.
Key Features
- 137℃ / 3–5s treatment secures thorough sterilization while safeguarding the sensory and nutritional profile of dairy and beverages.
- High heat recovery reuses outgoing product heat to preheat the incoming stream, cutting steam and cooling-water demand.
- Dual filling support – hot filling with automatic discharge-temperature regulation plus cold filling – fits diverse line layouts.
- Compact plate architecture keeps the machine small and serviceable, easy to slot into new or existing plants.
- Full PLC automation with touch-screen display enables stable, hands-off production and clear process visibility.
How It Works
Cold product is pumped into the plate exchanger’s recovery section and preheated by the returning hot sterilized stream. It then enters the heating section, is raised to sterilization temperature, and is held briefly in the tube to complete UHT treatment before rapid cooling.
Standard process route:
5℃ → 65℃ (homogenization) → 137℃ (3–5s holding) → 20–25℃
(Suitable for aseptic cold-filling production.)
